extent(s) specified by the XTNTLTS parameter. For example, when you copy only the “dataset 2", the copy
operation processes as shown in Figure 58 .
Figure 58 Copying a Dataset by Using TSO (FCESTABL) Command with XTNTLTS Parameter Specified
Procedure for Volume Copying
To perform volume copying by using the TSO command (FCESTABL):
1. Set the T-VOL to offline, or set the ONLINTGT parameter of the FCESTABL command to YES before
proceeding to the next step.
2. Without specifying the EXTENTS and XTNTLST parameters, execute the FCESTABL command.
3. Change the VOLSER of the T-VOL.
NOTE: When VTOC is copied, the VOLSER of the S-VOL and the T-VOL will become the same.
This step must be performed before setting the volume specified as the T-VOL back to online.
4. If the T-VOL is set to offline in step 1 , set the T-VOL back to online.
This step is not necessary if the ONLINTGT parameter of the FCESTABL command is set to YES.
Procedure for Dataset Copying
To perform dataset copying by using the TSO command (FCESTABL):
1. By using the VTOC list stored in the S-VOL, check the VTOC (INDEX, VTOC, etc.) and the position of
the extent (CCHH, size) used for the dataset copy operation.
2. Create the copy target dataset on the T-VOL.
3. Acquire the VTOC list stored in the T-VOL.
4. Set the T-VOL to offline, or set the ONLINTGT parameter of the FCESTABL command to YES before
proceeding to the next step.
5. Execute the FCESTABL command with the XTNTLST parameter.
NOTE: By using the XTNTLST parameter of the FCESTABL command, you can specify the
information on the source and target extents. When there are multiple extents, specify the
information on all the extents of the relevant datasets.
FlashCopy Mirror Version 2 allows you to use the XTNTLST parameter in the following ways.
• You may specify multiple copy target datasets to be copied simultaneously from a single copy
source dataset.
• You may specify the simultaneous execution of volume copying and dataset copying from a single
source volume.
• You may specify multiple source datasets that are overlapping or are an inclusive part of another
dataset. However, the number of extents that you may specify per dataset is limited to 16.
• You cannot specify multiple target datasets that are overlapping.
• You may specify source and target datasets that differ in position.
• You may specify the source and target datasets that are in the same volume, provided that they do
not overlap.
